We have a third party developer who has tested his software under the Community Edition JBoss-AS 5.1.0.GA. Howver, we are running the RHEL version JBoss-AS 5.1.1-GA Enterprise Edition. Allthough I know most things are backwards compatible, we have seen tiny differences (for example in classloading methods, etc) over the versions. To accommodate the software developer (who seldomly has enough resources to buy a license for the Enterprise Edition), I have one question:

What is the version of JBoss-AS Community Edition which is best comparable ti the JBoss AS 5.1.1 GA Enterprise Edition of RHEL ? Then we can put this version in our rules and guidelines.

An earlier post asked about the trial period for JBoss EAP and what happens when the trial period expires. The response from someone on the JBoss team was that the poster could continue to use EAP, it would just be that the poster could not get support. Therefore, your developers could download the EAP trial and use that to do development work without having to do purchase support.
